This invention relates to a positioning device for a stapling machine adapted to position fabric wicks around wire wick supports in preparation for stapling the wicks to the supports.

The stapling machine itself does not constitute part of my invention; it may be of any conventional type, poweror hand-operated, and preferably includes provision for automatically feeding staples to the dies as is well known in the art.

My device is designed to provide a simple and economical means for positioning wicks and wick holders in such a machine in preparation for the stapl'n'g operation, and to permit ready removal of the stapled wick-and-wick-support assemblies. It is particularly adapted to handle wicks and supports such as are employed to diffuse deodorant or performing vapors from a liquid contained in a bottle into the air of a room.

} Such wicks are usually strips of woven or felt fabric doubled over and stapled to a wire support. The latter is of a suitable shape, size and material to retain the wick by friction in the neck of the bottle at any desired height. A typical wick may, for example, be a felt strip 12-14 inches long, %-1 inch wide and /8 /4 inch thick, but these dimensions are not limiting.

My device consists essentially of a long narrow base plate with means to position the forward end firmly about the lower die or anvil of the stapler, a sliding member mounted in guides on the base plate and having a hook or other means at the forward end to engage a wick support, a tension spring or other device at the rear end for retracting the sliding member, a detent on the sliding member and a trigger on the base plate for holding the sliding member in extended position, and guide means mounted on the base plate for guiding a wick and associated support into stapling position.

One embodiment of my invention is described in detail in the following disclosure and in the drawings, but these are intended to be illustrative only and not to limit the invention, the scope of which is defined in the appended claims.

In the drawings:

Fig. 1 represents my positioning device mounted on a conventional foot-operated stapling machine;

Fig. 2 is a plan view of my device with the sliding member in extended position and a wick and wick support in place;

Fig. 3 is an end view of my device as seen viewing Fig. 2 from the right, but without the wick and wick support;

Fig. 4 is a side elevation of my device as seen viewing Fig. 2 from the trigger side;

4 Claims. (CI. 1 -3) Fig. 5 is a plan view of the forward end of my device with the sliding member retracted, showinga wick and wick support in position after stapling; and

Fig. 6 is a perspective view of a wick-and-wicksupport assembly before placing in my positioning device.

Base plate I is provided with an annular boss 2 at its forward end having set screws 3 by which it is firmly mounted on the lower die or anvil 4 of the stapling machine. The base plate is also provided with guides 5 in which slides the sliding member E. An eyebolt 1 is mounted on the rear end of the base plate.

Sliding member 6 is provided with ahook 8 at its forward end, a wedge-shaped detent 9 near its center and an eyebolt l0 just behind the detent. A tension spring H connects eye-bolt i and eyebolt l0, and tends to retract slide '6 to the left, as shown in the drawings.

Mounted on base plate I is a trigger l2 pivoted between posts l3. A compression spring I4 urges the outer end of .the trigger upwards to bring its inner end into engagement with detent 9 when sliding member 6 is drawn to the right as seen in the drawings, and thus to retain the sliding member in this position against the pull of spring ll.

Also mounted on plate I is a guide assembly for guiding a partially assembled wick and wick support when my device is in use. This guide assembly consists of two short channel bars [6 mounted on the base, a cross bar I! bridging them at their forward ends and two adjusting screws l8 with associated lock nuts. The channel bars [6 are preferably mounted at a slight converging angle with channels facing each other as shown.

My device is shown in Fig. 1 mounted on a conventional stapler operated by a pedal [9. Depression of the pedal operates the stapling head by means of pitman 2|. The stapling head 20 is pivoted at 22. It includes a device for feeding staples to upper die 23.

In operating my device a wick 24 is loosely threaded through the upper loop 25 of a wire wick support 26 with one end of the wick extending some 2-4 inches further than the other, as shown in Fig. 6. Sliding member 6 is drawn forward until detent 9 is engaged by trigger l2, and loop 25 is passed over hook 8 as shown in Fig. 2. The outer end of trigger I2 is depressed, releasing sliding member 6 which is retracted by spring II. This draws the wick and its wire support through guide assembly l5, thus folding the wick tightly over the support by action of the bar l1,

3 l forcing together the tips 21 of the bowed legs of the support and positioning the wick and support tips under the upper stapler die 23. Depression of stapler head 20 by means of pedal l9 then inserts a staple 28 through both layers of wick and clinches -it around tips 21 of support zfi 'asshown; in Fig. 5. Wickand sliding member are then drawn forward until trigger 12 again engages detent 9 and the stapled wick-and-wick support as;-

sembly is removed from hook fl he d evice is then ready for a repetition of the-"operation;

From the above description it will be cleartE those skilled in the art that variousgnodiii'cations g maybe introduced into my device departing mmthe scope of my invention as defined in the claims.
